Thermophysical Properties of Natural Refrigerants



Joe W. Magee


Natural refrigerants are candidates to replace halogenated hydrocarbons as working fluids in refrigeration systems. This class of substances is loosely defined to include carbon dioxide, ammonia, water, air, nitrogen, hydrogen, helium, light hydrocarbons, and mixtures of these substances. Accurate thermophysical properties are prerequisite knowledge to design efficient and cost-effective refrigeration systems which use natural working fluids. A review is presented for experimental methods and measurements of heat capacity, density, and vapor pressure. These properties are key to an understanding of fluid-phase behavior and the design of refrigerators.
